Cross-Posting Guide
Post to Threads and Instagram from one composer
Threads first, Instagram expansion. Both Meta platforms in one workflow.
Quick answer: To post to Threads and Instagram at the same time, use Socialync. Upload your video once, pick Threads and Instagram, write a caption for each, then post now or schedule it. Both go live at the same moment. Posts you make in the Threads app stay on Threads, so post from Socialync when you want both. It's free for 5 posts a month with no credit card.

The multi-platform posting is seamless. My content reaches 3x more people with zero extra effort.
Simple dashboard, easy sign-up, and the scheduling is so nice. If I make 10 videos in one day I can schedule them to all platforms weeks in advance. Goated!
I built this because I was burning out posting manually. Now I post in 3 minutes instead of 45.
